WATCH-BOW res'rnivnn.

Specification of Letters Patent. Patented Ap g 19, 1921,

Application filed November 5, 1920. Serial No. 421,854.

To all whom it may concern:

Be it known that I, EDWARD J. VVITTMAN, a citizen of the United States, residing at Elgin, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Watch-Bow Fasteners, of which the following is a specification.

This invention relates to a novel construction for securing a bow to the pendant of a watch case, and has for its principal objects a construction wherein a secure fastening is obtained with a minimum of expense and labor.

An embodiment of this invention is shown in the accompanying drawing in the manner following:

Figure 1 is a face view of a watch equipped with a pendant to which the bow is secured by my invention;

Fig. 2 is an enlarged detail, partly in longitudinal section, illustrating the construction of the fastening means; and

Fig. 3 is a plan view thereof, but partly in horizontal section, illustrating on an enlarged scale the watch bow fastening, one of the fastening means being only partially in place.

In the drawings I have represented a watch having a case center A which is provided with a pendant B to which is fastened a bow C by the means which constitutes this invention. As best shown in Fig. 2, the pendant is formed with oppositely disposed shoulders 5 each having therein a longitudinal bore 6 adapted to receive a pin 7 which also extends through the ends of the bow so as to provide therefor a pivotal mounting. Extending upwardly from the pendant is a neck 8 which is surrounded by an annular groove 9 that is formed in the pendant between its shoulders 5. Each bore 6 communicates with this groove which at the points of intersection is deepened by a transverse bore so as to provide in effect pockets 10 at the end of the two bores.

To a pendant so constructed, the bow C may be pivotally connected in the manner explained. Each pin 7 is provided with a head 11, as shown, and in assembled relation the parts will occupy the position shown in Fig. 2. During the process of assembly, the two pins 7 will be required to move through the position that is shown at the left hand side of Fig. 3. When completely inserted, as shown at the right hand side of that figure, an appropriate tool may be used to bend or flatten down the extremity 12 of each pin, so as to cause it to lie partially within the associated pocket 10. In this manner the pin is deformed at its inner end so as to resist withdrawal from operative position.

It is to be noted that the construction which I have described is exceedingly simple and may be inexpensively produced. The presence of the pockets which lie beneath the extremities of the pins are entirely concealed from view, and this is true also of the groove 9 when the crown D is applied in place. For these reasons the parts which lie within the groove are not apparent and, if desired, may be unsightly without detracting from the appearance of the watch.

I claim:

1. In combination, a watch pendant pro vided with a pair of oppositely disposed shoulders on each of which is formed a bore that alines with the other, there being an annular channel between the two shoulders which intersects each bore, and a pocket formed in the channel at each such point of intersection, a bow having its ends arranged adjacent the pendant shoulders, there being in each bow end a bore adapted to aline with the bores in the shoulder, a pin connection extending through each bow end and proximate shoulder, the pin end lying toward the center of the pendant being disposed within the annular channel and having a bend toward the pocket therein, and a crown associated with the pendant arranged partly within the annular channel in a manner to conceal the bent ends of the pin therein substantially as described.

2. In combination, a watch pendant provided with a pair of oppositely disposed shoulders in each of which is formed a bore lengthwise thereof, there being a second bore intersecting with each of the others, a bow arranged to present its ends adjacent the pendant shoulders and provided with bores adapted to register with those lying lengthwise of the pendant, a pin extending through the bore of each bow end and proximate shoulder, the end of each pin lying toward the center of the pendant being deflected into the insecting bore, and a crown associated with the pendant in a manner to conceal the opening of each said intersecting bore, substantially as described.

3. In combination, a watch pendant provided with a crown and with a pair of oppositely disposed shoulders in each of which is formed a bore lengthwise thereof, there being a second bore intersecting with each of the others and continuing therebeyond to form a pocket, the open end of each intersecting bore being disposed beneath the crown, a bow having its ends arranged adjacent the pendant shoulders, there being in each bow end a bore adapted to aline with one of the bores formed lengthwise of the shoulder, and a pin connection extending through each bow end and proximate shouL der, the pin end lying toward the center of the pendant being disposed transversely toward the pocket therein, substantially as described.
